Ag2s Solubility in Sulfide Solutions up to 250°C in Order to Estimate Possible Silver Sulfide Complexes in Ore Solutions, the S
Geochemical Journal, Vol. 21, pp. 291 to 305, 1987 Ag2S solubility in sulfide solutions up to 250°C ASAHIKO SUGAKI', STEVEN D. SCOTT', KENICHIRO HAYASHI', and ARASHI KITAKAZE1 Institute of Mineralogy, Petrology and Economic Geology, Faculty of Science, Tohoku University, Sendai 980, Japan' and Department of Geology, University of Toronto, Toronto M5S 1A1, Canada' (Received December 2, 1987: Accepted February 22, 1988) In order to estimatepossible silver sulfide complexes in ore solutions, the solubilityof Ag2Swas measuredbetween 25° and 250°Cin NaOH-H2S-H20solutions of 0.0 to 4.1m NaHSconcentration. Solu bilitychanges as a functionof temperature,total reducedsulfur concentration ES (mHS + mHS-)and pH. A maximumsolubility of 2140ppmAg was obtained at 250°Cin 4.1m NaHSconcentration under PH 2Sof 29.1 atm. From these solubility data, reactions to form silver sulfide complexes are estimated as follows: Ag2S + H2S = Ag2S(H2S), Ag2S + H2S + HS = Ag2S(H2S) (HS)-, Ag2S + H2S + 2HS = Ag2S (H2S) (HS)22 and Ag2S + 2HS = Ag2S (HS)22-. The equilibrium constants for these reactions are given in Table 2. Assuming that such silver sulfide complexes as above are in an ore solution , Ag2S (argentite or acanthite) is precipitated in response to changes of temperature, pH and total sulfur concentration (ES). Decrease of pH and ES is more effective than that of temperature. Silver sulfide complexes are more important than silver chloride complexes in ore solution of high ES, neutral to slightly alkaline pH and geologically reasonable chloride concentrations. INTRODUCTION to the experimental study by Seward (1973), Thermochemical data for aqueous metal bisulfide complexes are significant for the trans species at elevated temperatures and pressures port of gold in ore solutions under epithermal are indispensable for understanding transport of conditions, even if chloride complexes have the metals in hydrothermal solution. -
An Investigation of the Crystal Growth of Heavy Sulfides in Supercritical
AN ABSTRACT OF THE THESIS OF LEROY CRAWFORD LEWIS for the Ph. D. (Name) (Degree) in CHEMISTRY presented on (Major) (Date) Title: AN INVESTIGATION OF THE CRYSTAL GROWTH OF HEAVY SULFIDES IN SUPERCRITICAL HYDROGEN SULFIDE Abstract approved Redacted for privacy Dr. WilliarriIJ. Fredericks Solubility studies on the heavy metal sulfides in liquid hydrogen sulfide at room temperature were carried out using the isopiestic method. The results were compared with earlier work and with a theoretical result based on Raoult's Law. A relative order for the solubilities of sulfur and the sulfides of tin, lead, mercury, iron, zinc, antimony, arsenic, silver, and cadmium was determined and found to agree with the theoretical result. Hydrogen sulfide is a strong enough oxidizing agent to oxidize stannous sulfide to stannic sulfide in neutral or basic solution (with triethylamine added). In basic solution antimony trisulfide is oxi- dized to antimony pentasulfide. In basic solution cadmium sulfide apparently forms a bisulfide complex in which three moles of bisul- fide ion are bonded to one mole of cadmium sulfide. Measurements were made extending the range over which the volumetric properties of hydrogen sulfide have been investigated to 220 °C and 2000 atm. A virial expression in density was used to represent the data. Good agreement, over the entire range investi- gated, between the virial expressions, earlier work, and the theorem of corresponding states was found. Electrical measurements were made on supercritical hydro- gen sulfide over the density range of 10 -24 moles per liter and at temperatures from the critical temperature to 220 °C. Dielectric constant measurements were represented by a dielectric virial ex- pression. -

Prohibited and Restricted Chemical List
School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List PROHIBITED AND RESTRICTED CHEMICAL LIST Introduction After incidents of laboratory chemical contamination at several schools, DCPS, The American Association for the Advancement of Science (AAAS) and DC Fire and Emergency Management Services developed an aggressive program for chemical control to eliminate student and staff exposure to potential hazardous chemicals. Based upon this program, all principals are required to conduct a complete yearly inventory of all chemicals located at each school building to identify for the removal and disposal of any prohibited/banned chemicals. Prohibited chemicals are those that pose an inherent, immediate, and potentially life- threatening risk, injury, or impairment due to toxicity or other chemical properties to students, staff, or other occupants of the school. These chemicals are prohibited from use and/or storage at the school, and the school is prohibited from purchasing or accepting donations of such chemicals. Restricted chemicals are chemicals that are restricted by use and/or quantities. If restricted chemicals are present at the school, each storage location must be addressed in the school's written emergency plan. Also, plan maps must clearly denote the storage locations of these chemicals. Restricted chemicals—demonstration use only are a subclass in the Restricted chemicals list that are limited to instructor demonstration. Students may not participate in handling or preparation of restricted chemicals as part of a demonstration. If Restricted chemicals—demonstration use only are present at the school, each storage location must be addressed in the school's written emergency plan. Section 7: Appendices – October 2009 37 School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List Following is a table of chemicals that are Prohibited—banned, Restricted—academic curriculum use, and Restricted—demonstration use only. -
